Abstract

A supermultiplet of two spin‐0 and one spin‐ 1/2 particle in a Coulomb potential has been shown recently to possess a dynamical OSp(2,1) symmetry algebra. The canonical chain of maximal subalgebras leads to a natural choice of quantum numbers and state vectors. The relevant representations of OSp(2,1) are constructed in this adapted basis, and the wave functions subsequently obtained by going to a coordinate realization.
